How do I keep an nvidia raid 0+1 array from constantly degrading?

I have this new pc since about March, it works fine except that sometimes my raid 0+1 array (4x250Gb Maxtor disks) becomes degraded.

What happens is this: once in a while (lately quite often, thrice in 5 days) one of the disks "disappears", the pc doesn't recognize it anymore and the array gets degraded. Luckily everything keeps on working thanks to redundancy.

I switch off the pc. switch it back on and the disk gets recognized again: then I can use nvidia's mediashield utility to rebuild the array and all is back to normal until it happens again.

Important: the disk is NOT always the same. Sometimes it's one disk, sometimes another.

What could be wrong? I've checked all configuration options in the bios and control panel, it's all good...

Is there a way to convert the array to just 4 separate disks without losing any data and without reinstalling windows?

If the drives are SATA, the connectors may be marginal or may have oxidation, preventing good cantact.  I would clean those with an eraser to eliminate this.  It's also possible you have a power supply problem and the drives are not getting enough power.  Swap it for another one to see if this is the cause.

I don't think it's the power supply, it's a 700W power supply made especially for sli configurations. Can the connectors have oxidation even after some months? What do you mean by marginal (I'm italian...)?

I mean it is right on the edge of failing, and sometimes works and sometimes doesn't, like an engine that needs tuning.  Check the hard drives with the manufacturer's diagnostic; a bad drive can sometimes make others behave badly also.  The disagnostics can be found on the UltimateBootCD, which you can download for free.
